r TO ALL-WHOM IT MAY COZSCERN:

Be it known that LJULIUS HACKEn'r, of 450 Fifth street, New York, in the county and State of New York, have invented a new and useful Improved Metal Compound; and Ido hereby declare that the following is a i'nll clear, and ekaet description thereof, which will enable those skilled in the art to make and use the same.

This invention refers to a compound of cream of tartar, snltpetre, copper, bolnx, zinc, :i-nd tutty, which, whenproperly prepared, forms a tough, ductile mass; similar in its appearance to gold, not liable to tarnish by the action of the atmospheric nir, and enpnbleof' withstanding the influence of weakneids nnd nlkalies.

The ingredients which I use in preparing my compound are mixed together as follows: I tnlte half at pound of cream of tartar, heat it in a suitable vessel to a red heat, and then add one ounce of snltpctre. In another vessel or crucible l melt half :1 pound of copper, and then I pour the fluid metal into the vessel containing the cream of tartar and snltpetre. To this compound I add the following ingredients horux, one ounce; metallic 'zinc, one ounce; tutty, one ounce; and when the mass is thoroughly and evenly mixed, I-pouk it into moulds of the required shape. The metal compound thus obtained has a reddish yellow color, imparted to it by the mixture of cream of tartar and saltpetre, whereby its appearance is'rendered similnr'to gold; it is very tough and ductileyit can be rolled out into sheets of any desired thickness, and worked into articles of different nature; it does not tarnish by the influence of the atmospheric air, and it is not attucked by weak neids and alkulies. For these reasons it is particularly applicable for spoons and forks, and it can also be used with good advantage for dental purposes, that is to say, for making the buses nndplutes and other parts ofnrtificinl dentures.

What I claim as new, and desire to secure by Letters Patent, is- A metal compound mode of the ingredients herein specified. and mixed together substantially in the manner end'ebout in the proportion set forth.

Also the addition of saltpetre and cream of tartar to n compound pf copper and zinc, substantially as and for the purposes described.

JULIUS HACKERT.
